The purpose of this research is to know the implementation of brainstorming method in group investigation model in Economic subjects and improvement of activity and learning result of students of class X IPS 3 SMAN 1 Batu. Methods of data collection using observation, test questions and field notes and analyzed by qualitative descriptive technique. The result of this research are: (1) improvement of student activity 18,71% from cycle I to cycle II, that is 63.30% cycle I and 82.31% cycle II; (2) the improvement of student learning outcomes is 22.22% from cycle I to cycle II, which is marked by the increase of 70.37% complete student in cycle I and increased to 92.59% cycle II. Implementation of brainstorming method in group investigation model is expected to be used as an alternative model of economical learning that is more innovative to improve student activeness. It is also expected that Economics teachers should implement the implementation of this learning model not only on the discussion of payment system and non-cash payment instruments only, but for other materials that have problems and materials related to the daily life of the students so that students are easier to find the latest information needed to be used as reference material. The results of this study are expected to be used by other researchers as a reference in carrying out the development of similar research. In addition to measuring student activity as well as learning outcomes, other researchers are expected to be able to measure other aspects such as critical thinking skills, communication skills, and so on, so that the results of research become more perfect.
